Ford 7.3L Power Stroke (1999-2003) :: Battery Light On / Voltage Meter Only Show Barely 12 Volts At Full Throttle

The brief information:

1. Stuck/non moving in traffic on the freeway for roughly 1 1/2. During that time the AC was running, but once I noticed my "battery light" on the dash turn on, I turned everything off.
2. Since then while on my way home from work the voltage meter only showed barely 12 volts at full throttle.
3. I charged my battteries, and started it up today to go into work. While going to work the voltage meter showed 14 at its high point, but shortly there after it dropped back down to 12. At which time the battery light came back on.

New battery or alternator?

Prius (Gen 2) :: 2003 - Code P3000 / High Voltage Leak

I bought an 03 with 58K miles on it. shortly after I bought it the check main battery light came on, the local Toyota dealer told me I needed a new main battery.

I had a P3000 code, a high voltage leak. It turned out to be corroded buss bars and cables, with 2 leaking cells, $1,450.00 latter the onboard computer said the problem was fixed and my display read normally for about 1,500 miles before I started getting that code and the check main battery light again.

I took it back to the shop tat did the work and they ran the diagnostic's on it again, checking the main power cables that led from the main battery under the car to the Toyota Hybrid system, inverter? under the hood they checked all of the high voltage connections, they all checked out fine. The shop then took several days to do an online search for possible causes.

This led to the CV trans axle with its electric motors and generators as the possible culprit. The car is running and driving fine, so I did the 60,000 mile transmission oil change, suggested by my mechanic ( apparently the fluid becomes conductive with age) the check battery light will go off if I remove the secondary battery terminal for a minute or so and stayed off for 2 tanks of gas after the fluid change but it did come back on.

I can reset the computer easily enough and it will stay off for 3 to 400 miles but I'm looking to get the damn light to stay off. I'm going to change the trans fluid again. Changing drive motor or generator?, can this be done in the car? or at all? It may be that if this is the problem it may end up making sense to just put in a new CV transaxle.

Prius (2004-09) :: Long Term Storage Of High Voltage Battery

I have an opportunity to get a high voltage battery from a salvage Prius. I don't need a replacement now but thought having an extra battery would be a good idea. How long can the battery be stored? Maybe switch them out every few months to keep both charged?

Prius (2004-09) :: Code C1241 - Auxiliary Battery Abnormally High Positive Voltage

2005 Prius shows a C1241 code, which can mean abnormally high or low positive voltage in the auxiliary battery. In my case it appears to be abnormally high, because my voltmeter showed the battery charged to 18 volts with the car off, and when running it showed 20 volts going to the battery. There's also a POA80 code (hybrid battery pack) but I'm not convinced yet that it's a hybrid battery problem. What would cause the overcharging of the auxiliary battery?

Prius (Gen 2) :: Upgrading To HID Bi-Xenon (low And High Beam) And Aiming Headlight?

After months of researching and foruming, I made a satisfied decision to upgrade from Halogen to aftermarket HID Bi-Xenon which is really great in color and high visibility at night.

Moreover, behind Halogen headlight there is a 8mn bolt where you will use your hand or 8mn wrench (remove the black plastic cover over bumper to make more room). Twist it Clockwise to lower and Counter Clockwise to raise headlight.

I aimed mine relatively low because my intention is for a great looking light, high visibility and not blind on-coming traffic and yeah I'm so satisfied.

Ford Excursion :: High Voltage Junction Box?

Today I'm installing a UHF/VHF radio in the X and after I got the cable run through the firewall I started looking for either a) the best route to the battery or b) a junction box the PO put in of which I have many.

So as I'm poking around on the drivers side of the engine compartment I find a large bore wire that terminates into a junction block with 'caution, high voltage' printed on the cover. This is right under the area where all the other junction blocks, relays and alarm from the PO are. Unfortunately the PO used wire who's gauge is to small for my current needs.

The block in question is shown in the following photos. It can easily be seen just left of the 86 written on the side of the relay. You can see a bit of red positive cable going into the black box below the relays. My question is if this is an OEM box or something aftermarket.

Zoomed in: Large gauge wire with red entering the box

Zoomed out for reference

Ford :: 1999 - Melted EEC Diode / High Voltage

i just got a 1999 ford explorer with a 4.0 SOHC it runs fine except it came with a bad alternator and a melted EEC diode. So I put in a new alternator and diode, but it was putting out 15.5V and melted the new diode in two days . So I took it back and they said it was bad and gave me a new one. After i put this one in it gave me 16.5v and melted the new new diode in one day. I took this one back and they said it was fine and only putting out 15V. Is there anything else that can give me high voltage and melt a diode beside the alternator?

Phaeton :: CEL Came On - Getting Error Coolant Temp Sensor High Voltage?

My CEL came on and the code said Coolant Temp Sensor High Voltage. Since there are 2 sensors, and my gauge isn't reading off, about 200F constantly, I assume the bad sensor is the water pump sensor. Also, is there a diagram of the sensorny locations and the easiest way to access them to swap them out. I have already purchased the sensor and gasket, just don't want to replace the wrong one or screw something else up in the process. It appears to be an easy job.

Ford F-150 (2009-2014) :: Battery Light On - Voltage Too High?

So, I get back from vacay and find my baby has a new issue.... the "battery" light came on just after I started it up after my 10 days away.

I can drive it seemingly ok, it did do some cool flashing and lost display and radio on one trip but now it seems not as bad.

I did a volt meter chack on the batt terminals and have 12.3 or 12.4 with key off and 14.9 with engine running. I turned on the headlights and rear defroster and get 14.6V on the terminals. 21.6A running to the main fuse block right by the rad,

Jeep - Grandcherokee :: 1998 - P0138 Code / O2 Sensor High Voltage

I drive a 1998 Jeep Grand Cherokee, 6 cylinder engine, with about 120,000 miles on it. I used a code scanner and pulled a P0138 code-bank 1 sensor 2 O2 sensor high voltage, if I'm correct. First of all, it looks like this sensor is after the catalytic converter, right? So I think I either have a bad 02 sensor or a bad catalytic converter. What are the consequences of driving around without fixing this? Will I see any reduction in fuel economy, or any potential long-term problems elsewhere?

Lexus SC430 :: What Is Normal Voltage When Fully Charged And Minimum Voltage To Crank Starter

After not driving the car for over a week, the battery was dead and I discovered that I had not fully shut the trunk. I hooked up a charger/maintainer with the battery still installed in the car and it has been on for 48+ hours and it still shows as charging. I have several of the chargers and use them on other cars/motorcycles where they work as expected. I've never had one take this long to indicate charged.

I'm sure others are using maintainers and wondering if it is normal that the charger does not indicate full charge. Voltage with charger running is ~14.7 and ~13.7 unhooked. I believe it is a 4a charger.

What is normal voltage when fully charged and what is minimum voltage to crank starter?

Should have measured the voltage before hooking up the charger to know low it was......

Prius (2004-09) :: 2006 - Passenger Side High Beam And Driver Side Regular Headlight Went Out

My 2006 Prius (Model NHW20) has a strange headlight problem. On the passenger side, the high beam light is out but the regular headlight works.

On the driver side, the high beam is working but the regular headlight is out.

I don't think it's the fuses but I'm not sure. No amount of interchanging the following fuses changes anything about the issue:

1. 10A H-LP HI RH
2. 10A H-LP HI LH
3. 15A H-LP LO RH
4. 15A H-LP LO LH

Ford 6.0L Power Stroke Diesel :: 2006 F350 - High Voltage Blanks Instrument Cluster

Got in my 06 F350 dually 2 weeks ago and after start up had no instrument indications. Truck ran great, flat line on panel. Tow haul light out also. Drove it for appx 5 miles, shazam all start working and then they cycled on and off for a while. After 10 miles, came on solid. Happened again at a later date.

Here's what I discovered. I noticed high voltage on my Scangage II. As in 16.2VDC. Monitored it coming back from a hunt. 14.9-15.5VDC. Would blank out only after hitting 16.2VDC. I'm suspecting there might be a cutout to protect the instrument cluster from damage.

Installed a new alternator on Friday the 13th. Drove home this weekend, 4 hours and no problems. Hopefully didn't boil off the batteries. Now 13.5-13.9VDC ... Just something to be aware of!!

Caravan/Voyager :: 2005 Town Country - P0032 Oxygen Sensor Heater Circuit High Voltage

P0032 Oxygen Sensor Heater Circuit High Voltage (Bank 1, Sensor 1)

I have read that in 2005 chrysler changed the ohms levels for the oxygen sensors and may need to have bcm reflashed to get a new oxygen sensor to work wheither its dealer item or not, is this true if i were to buy a mopar oxygen sensor? aftermarket is out of the question being the ohm readings would require me to spend some time at the dealer. is this code a defective sensor? or could it be related to the thermostat being faulty? am not low on antifreeze and temp gauge reads normal.
